For the preceding problem, also determine (a) The conditional probability mass functions pR|G and pG|R. Are R and G independent? (b) E[R] and E[G]

(c) Var(R) and Var(G)

(d) cov(R, G)

THIS IS THE MENTIONED PRECEEDING QUESTION, I DON"T NEED THE SOLUTION TO THIS ONE (JUST THE QUESTION ABOVE)

2. Three balls are selected at random from a bag containing 3 red, 3 green, and 4 blue balls. Dene the random variables R = the number of red balls drawn, and G = the number of green balls drawn. List the values of (a) the joint probability mass function pR,G(r, g). (b) the marginal probability mass functions pR(r) and pG(g). (c) the joint distribution function FR,G(r, g). (d) the marginal distribution functions FR(r) and FG(g).
